This program allows you to view an extended Fibonacci Sequence. You can view the normal Fibonacci Sequence by entering "2" when prompted, as each number is the sum of the two before it. Similarly, enter "3" to have a sequence with each number being the sum of the last three numbers. This is sometimes called the tribonacci sequence. You can enter in any number between 1 and 20; after 20, it takes too long to calculate.
